## When to prefer this

Choose this endpoint when you need automated detection of flash crash conditions or circuit-breaker halt signals from raw market data strings, especially in algorithmic trading pipelines, market surveillance systems, or post-incident analysis workflows where a dedicated flash-crash-specific model is required rather than generic volatility analysis.

## Known failure modes

- Malformed or empty data string returns validation error
- Ambiguous or non-financial data may produce unreliable results
- Service unavailable if API host is down, returning 5xx error
- Insufficient data context may result in low-confidence or indeterminate halt signal
- Payment failure via x402 protocol blocks request processing
